A tan or green dye is obtained from the needles;
The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat;
A fairly wind resistant tree, it can be grown as part of a shelterbelt planting;
Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile; The resins are obtained by tapping the trunk, or by destructive distillation of the wood; In general, trees from warmer areas of distribution give the higher yields; Turpentine consists of an average of 20% of the oleo-resin; Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc; Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc; Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.
Wood - light, soft, close-grained. It is occasionally made into lumber and is also used for general carpentry;
